At the four corner positions at the bottom of the left fixing plate 401 and the right fixing plate 402, fixing rods 403 for inserting into the soil layer are fixedly installed. There are multiple groups of fixing rods 403.

[0048] The utility model provides a sampling device for surface soil quality analysis and testing, and its working principle is as follows:

[0049] (1) Assembly between the sleeve 1 and the fixing mechanism 4

[0050] The sleeve 1 is clamped by the left fixing plate 401 and the right fixing plate 402; then the limiting block 404 is installed at the position where the left fixing plate 401 and the right fixing plate 402 are in contact; by rotating the screw 405, one end of a screw 405 is embedded into the interior of the left fixing plate 401 through the limiting block 404; one end of the other screw 405 is embedded into the interior of the right fixing plate 402 through the limiting block 404; thus, the left fixing plate 401 and the right fixing plate 402 are fixed to the upper part of the sleeve 1.

[0051] (2) Place the sleeve 1 in the soil where sampling is required, and at the same time, the bottom of the fixing rod 403 is embedded in the soil. By the cooperation of the fixing rod 403, the left fixing plate 401 and the right fixing plate 402, the stability of the sleeve 1 during soil sampling is improved.

[0052] (3) Operate the adjustment mechanism 2 to drive the sampling collection tube 3 to move to the right, so that the sampling tubes 301 at different heights extend into the soil layer for sampling:

[0053] The specific method is as follows:

[0054] Push the limit rod 201 to move downward along the outer wall of the support rod 202; when the limit rod 201 moves downward, push the first fixed seat 206 downward; since the second fixed seat 207 is fixed to the limit rod 201, therefore, when the limit rod 201 pushes the first fixed seat 206 downward, the spring 208 will be compressed; at the same time, when the limit rod 201 pushes the first fixed seat 206 downward, it will drive one end of the push rod 204 hinged to the first fixed seat 206 to move downward, and the other end of the push rod 204 will drive the movable connecting rod 205 hinged to it to rotate to the right around the connecting plate 203, thus giving the sampling collection tube 3 a rightward acting force and pushing the sampling collection tube 3 to move to the right. Therefore, the sampling collection tube 3 overcomes the acting force of the leaf spring 304 and moves to the right, realizing that the sampling tube 301 is inserted into the soil layer at different depths and achieving the effect of soil sampling;

[0055] When the sampling is completed, cancel the thrust applied to the limit rod 201; on the one hand, the limit rod 201 moves upward and resets under the action of the spring 208, thus reducing the rightward thrust on the sampling collection tube 3; on the other hand, under the action of the leaf spring 304, the sampling collection tube 3 moves to the left around the hinge point with the support seat 304, so that the sampling tube 301 moves into the inside of the sleeve 1 to complete the soil sampling.

[0056] In this application, a rotating rod 209 is installed at the top of the limit rod 201, which has two advantages:

[0057] First, it is convenient to operate the limit rod 201 to move downward.

[0058] Second, the top of the sleeve 1 is higher than the left fixing plate 401 and the right fixing plate 402, so that a groove is formed at the top of the sleeve 1. The length of the rotating rod 209 is longer than the diameter of the sleeve 1. Therefore, the up and down stroke of the rotating rod 209 can be limited, and thus the movement of the limit rod 201 can be limited.

[0059] (4) After the sampling is completed, pull out the sleeve 1 from the soil, open the baffle 305 of the sampling tubes 301 at different heights to make the baffle 305 in an open state, and take out the soil from the sampling tubes 301.

[0060] The utility model provides a sampling device for surface soil quality analysis and testing, which has the following advantages:

[0061] (1) Set the adjusting mechanism to drive the sampling collection tube to insert into the soil layer. Therefore, the thrust for inserting the sampling collection tube into the soil layer is increased, and it is applicable to soil sampling of hard surface soil with a relatively high density.

[0062] (2) The sampling collection tube is provided with sampling tubes at multiple different heights, which can simultaneously sample soil layers at different depths and improve the sampling efficiency.

[0063] (3) By setting the fixing mechanism, the stability of the sleeve during soil sampling on the ground surface is improved.

[0064] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
